July 19, 2015. Trail is in great shape. Several patches of shade along the way shrouded in Redwoods, Pines, Firs and Dogwoods. Beautiful distant views. Nothing but peace and quiet. Zero poison oak. Best trail out of Twain Harte.

This a nice walk. Of course it is the old rail road grade so it's flat and easy to traverse. No fear of getting lost on this one. The reward is reaching Lyons Lake which is very pretty. The trail is good for someone who is wanting a greater challenge in distance without something too rugged. As a matter of fact getting to the lake can be a little boring and then returning the same way you came can be more boring. But there are few 10 mile treks this close to civilization and it is worth exploring. This trail is perfect for a mountain bike ride even for kids. Bring water and food because it is a long way in and out.

Did the 2.4 mile hike down hill from SR. 108 park at closed scales and walk down. Gravel all the way with daughter on bike. Walk back up is a climb but flat wide rodeway.

Easy trail, great for running, hiking, biking. Lake is owned by PG&E so no swimming. Swimming with caution in river above lake is permitted. In winter, lake freezes over toward inlet. Do NOT try to cross the ice. Fishing for planter Trout is great and watching the Eagles fly is spectacular. Overall a great trail. Access from South Fork Rd., HWY108, or Confidence/ Middle Fork Rd's...

Truly the gateway to adventure! Whether from the east or from the west, this scenic mountain pass offers everything. If you're able, Sonora Pass by snowmobile is the way to go. Pack stations offer endless miles of horse trails. Also through Chipmunk Valley rock climbing and unbelievable vista hikes. Fishing and hunting opportunities are around every corner.
